In 1998, ten-year-old Natascha Kampusch vanished on her way to school in Vienna and spent the next eight years locked in a cellar built by her abductor, Wolfgang Priklopil, before escaping in 2006. This film builds her account largely through her own words, alongside interviews with her mother Brigitta, tracing the physical confinement and the psychological control Priklopil exercised over her during that time. Kampusch describes the conditions of the cellar itself and the tactics he used to keep her compliant, and she reflects on how she processed captivity as a child growing into adolescence inside it. The film also follows Brigitta through the years of not knowing whether her daughter was alive, and the eventual reunion after Kampusch's escape and Priklopil's suicide. Rather than sensationalizing the case, the documentary stays close to Kampusch's own analysis of what happened to her, including her insistence on being seen as more than a victim. It closes with her account of rebuilding a life afterward, on her own terms.
